More and more pressure technology is used in modern diesel engine, which makes the oil collector more power, more reasonable in the condition of constant volume, and saves energy greatly. However, in actual work, many drivers do not know much about the performance, structure and principle of turbocharger, and the damage of the turbocharger in short time is common, which not only causes great economic loss, but also affects the normal use of the diesel engine. How can we use proper maintenance to extend the service life of turbochargers?

1. Ensure the reliable lubrication of the turbocharger of Baotou North running heavy steam fittings, according to the specification of the turbocharger, the use of the required supercharged diesel engine oil (generally use CD grade advanced lubricating oil), and check the quantity and quality of the oil regularly, change the oil of metamorphic or dirty in time, clean or replace the oil filter. To ensure the high cleanliness of the oil.

2. To ensure the high cleanliness of the diesel engine intake, the sealing of the inlet and exhaust pipes of the turbocharged diesel engine must be kept, the air filter is regularly cleaned and maintained, the loosening of the screw nut or bolt, the clamping of the hose clamp, the leakage of the air intake system, the replacement of the gasket, so as to prevent the dust. And silt and so on are inhale in the compressor. Otherwise, the fouling can cause the air filter wall plug, compressor channel and Turbocharger Blade contamination, resulting in the pressure drop, and even lead to the early wear of the blade and diesel engine parts.

3. After starting the new diesel engine or the new diesel engine, the new diesel engine or the new supercharger must be added to the new diesel engine or the supercharger before starting, and the intake pipe joint on the supercharger must be unloaded and the oil of 50-60mL is added to prevent the ignition of the turbocharger bearing at the moment of starting.

4, before starting, the diesel engine should shake the rotation of the crankshaft to ensure that if the lubrication is possible, the oil should be filled with the oil filter and the whole lubrication system, and then the oil pressure is stable. Otherwise, the turbocharger bearing may be damaged due to lack of lubrication during start-up, because when the turbocharger is very high, the shortage of oil supply for the turbocharger bearing in a few seconds will cause damage to the bearing of the Baotou North running heavy steam parts.

5. After starting the oil cutter, the diesel engine should not be started immediately after the start of the high speed running diesel engine. It should operate at idle speed for a few minutes and then speed up the operation, otherwise it will easily cause the burning of the turbocharger bearing, especially when the diesel engine is replaced with lubricating oil, the supercharger, the filter or the replacement of the filter element and the parking more than one star period. Lower, the supercharger on the oil inlet joint to loosen a bit, until the oil spills tighten, and then intentionally, speed operation after 3-5 minutes can be loaded operation.

6, the diesel engine can not run idle for a long time or cause the engine oil to leak into the compressor and lead to the exhaust pipe oil injection, increase the oil consumption, while the long idle running, the oil pressure is insufficient, and it also easily causes the turbocharger to be poor lubrication and burn the bearings.

7. After the high speed and full load of the diesel engine, it should not be stopped immediately before the stalling and stalling of the diesel engine will turn around 5min, so that the parts of the parts of the Baotou North run heavy steam parts supercharger are not oil, the oil is overheated, the turbocharger bearings and turbine impeller are killed, and the oil seal is lost. At the same time, we should pay attention to whether there is a rub between the impeller and the shell of the supercharger when the diesel engine is stopped. If there is a rubbing sound, the supercharger should be removed immediately to check whether the clearance of the bearing is normal.

8. Periodic inspection, cleaning and maintenance of the supercharger are required according to the requirements of the instructions. The supercharger should be cleaned once every 1000 hours, and the compressor impeller should be cleaned once. The clearance of the impeller, the clearance between the rotor shaft and the floating bearing, the axial momentum of the rotor, the static balance and the dynamic balance of the rotor, etc., should be checked, adjusted, repaired or replaced if it is not in accordance with the regulations or damage.
